Converting the TERZ 94 into the TERZ 94-S
The TERZ 94 can be converted into a TERZ 94-S by installing another board.
•
Remove the battery (see chapter “Changing the battery”).
•
Remove the jumper for battery-powered mode (1-2) on the socket X2_0
of the board.
•
Srew the 4 short stay bolts onto the present stay bolts on the board.
•
Plug the current module TERZ94trm with a 12-pin connector (X2_1) into
the socket X2_0.
•
Apply the supply voltage (24V) to terminal X22 (1 +, 2 - ).
•
Switch on the power supply (24 V).
•
Check the current output:
−
Set the current output in channel A09 to I-Out (mode 1 or 2).
−
Channel C02: enter flow rate at 4 mA.
−
Channel C03: enter flow rate at 20 mA.
−
Set channel C04 (default value) to 10.0 mA.
−
Set channel C05 (output mode) to 1 (current output is proportional to
the flow rate).
−
Channel C06: enter correction value for the current offset (see value
on the board)
−
Channel C07: enter correction value for the current rise (see value on
the board)
−
In the event that a recalibration should be necessary, there is a PC-
based program available which will define the new offset and rise
values.
•
Now the TERZ94-S is operational.
